TROLLEY-GUIDE. f

SPECIFICATION forming part of Letters Patent No, 781,681, dated March14, 1905. Application filed December 21, 1904. Serial No. 237,845.

To ar/Z 11/71/0722, it may concern:

Be it known that L'JoHN F. J AMESON, a citizen of the United States,residing at Plimpton, in the county of Holmes and State of Ohio, haveinvented a new and useful Trolley-Guide, of which the following is aspecification.

In overhead electric-railway systems considerable difiicultv isexperienced in preventing the trolley from jumping from the trolley-wireor conductor when rounding curves, due to the lateral pressure upon atrolley, and the same difiiculty is met with in crossing a railway-trackor other track, Where the shaking and jarring movements of the car causethe trolley-pole to oscillatelaterally, and thereby displace thetrolley-wheel from the wire.

The object of the present invention is to overcome the objectionsaforementioned in a simple and effective manner and to embody theinvention in the nature of a guide for trolley-wheels which is completein itself and capable of being erected in the path of trolleywheels atcurves and railway crossings to maintain the trolley-wheel in propercontact with the trolley-wire or conductor, so as to preventdisplacement thereof by lateral strains upon curves and by the jarringand shaking movements of cars when passing a railway crossing.

\Yith these and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacrificing anyof the advantages of the invention.

In the accompanying drawings, Figure 1 is a perspective viewillustrating an embodiment of the present invention supported directlyupon a trolley wire. Fig. 2 is a cross-sectional view thereof. Fig. 3 isa plan view showing the device used upon a curve. Figs.

'4 and 5 are detail sectional views showing preferred methods ofsupporting the guide independently of the trolley-wire.

l l i r Like characters of reference designate corresponding parts ineach and every figure of the drawings.

The present device has been arranged for city and inter-urban use, thegeneral construction of the guide being the same wherever located, andit is also constructed to be supported from a single row oftrolley-poles in inter-urban use, between two rows of poles or othersupports, and also directly upon a trolley-wire without extraneoussupporting means when it is necessary to locate the guide between theusual trolley-poles.

The present guide includes a pair of substantially parallel rails ortrack members 1, provided at their lower edges with inwardlydirectedsubstantially horizontal flanges 2, from which it will be understoodthat each rail is in the nature of an angle-bar of substantially L shapein cross-section. At suitable intervals corresponding standards orhangers 3 rise from the outer sides of the rail members, with theirupper ends connected by the individual cross-bars at, there beinglongitudinal frame-bars 5 connecting the tops of the standards orhangers at each side of the device. As best illustrated in Fig. 1 of thedrawings, it will be noted that the ends of the rails are boweddownwardly, so as to insure an easy entrance of the trolley into theguide. It will of course be understood that the space between the tracksor rails of the guide is entirely open and unobstructed by the freepassage of the trolley-wheel therethrough. The general features of theguide are always substantially the same as thus far described withoutregard to the location thereof; but the manner of supporting the guideof course differs slightly according to its location.

\Vhen it is necessary to locate the guide between a pair oftrolley-poles and it is not desirable to erect a supplemental supportfor the guide, it is proposed to mount the latter directly upon thetrolley-wire, as shown in Figs. 1 and 2 of the drawings, wherein 6designates an ordinary trolley-wire or conductor, upon which the presentform of guide is supported by means of downwardly-tapered seats 7, whichhang from the respective cross-bars 4, with their lower ends recessed orto receive the trolley-wire, upon which the seats rest, and therebysupport the guide.

In interurbau use, as indicated in Fig. 5, wherein the trolley-wire 6 issupported upon the usual arm 8, extending outwardly from thetrolley-pole 9 and supported at its outer end by a brace 10, inclineddownwardly from the pole, the hanger-fran'ie of the guide is hung fromthe arm 8, to which it is secured, as at 11, in any suitable manner,with the trolley-wire located midway above the interval between therails 1 and 2-.

\Yhen the trolley-wire is supported between two series of poles 12, asin Fig. t, the guide is hung from the cross bar or member 13, whichextends between adjacent poles and to which the trolley-wire isconnected, the guide of course following the direction of thetrolley-wire, whereby it may be used upon curves, as shown in Fig. 3, aswell as upon straight portions of the trolley-wire.

Any ordinary or preferred form of trolley will cooperate with thepresent guide, as clearly indicated in Figs. 1 and 2, wherein 14designates a trolley pole or arm having the usual harp 15, with anordinary trolley-wheel 16 supported within the harp and capable oftraveling against the under side of the trolley-wire in the usualmanner. In order that the trolley may engage the present guide,guide-rollers 17 are mounted upon opposite sides of the harp uponextended portions of the spindle or axle of the trolley-wheel, theflange 2 of the guide-rails 1 being spaced to recei e the guide-rollersupon the upper sides of said flanges, the upstanding portions of therails ODOIiIiLIDg to prevent lateral displacement of the guide-rollers"from the track, and thereby to retain the trolley-wheel in properengagement with the wire so long as the guide-rollers remain upon theguide. It \Vlll now be understood that the ends of the guiderails arebowed or inclined downwardly to insure the guide-rollers engaging withthe upper side of the guide as the trolley-wheel enters between theguide-rails.

\Yhen the device is supported solely upon a trolley-wire, as in Figs. 1and 2 of the drawings, it is proposed to brace the same against lateralswinging movements by means of guys or braces 18, preferably in thenature of cables running from the lower portions of the terminal hangers3 and with their outer ends anchored in the ground in any suitablemanner (not shown) at a distance suliiciently remote from therailway-track to prevent inter :ference with the cars.

From the foregoing description it will be understood that the presentguide may be assembled upon the ground. and then elevated and bodilysupported upon the trolley-wire or upon a suitable support, as desired,and

socketed I therefore it is proposed to construct the devicecomparatively light, but of sufficient strength to withstand the lateralstrains of the trolley-pole. \Vhen the device is assem i bled in conunction with the trolley-wire, it

l l l does not interfere with the passage of trolleywheels and does notrequire any particular form of trolley-wheel beyond the addition ofguide-rollers upon opposite sides of the harp and concentric with thetrolley-wheel.

Having fully described the invention, what is claimed is w 1. In anoverhead-trolley system, the combination with a trolley-wire, ofguide-rails located at opposite sides of the wire and provided withcorresponding inwardly-directed substantially horizontal flanges, and atrolleywheel having guide-rollers at opposite sides to run between theguide-rails and upon the flanges thereof.

2-. A guide for trolleys consisting of a pair of spaced substantiallyparallel guide-rails, hanger members rising from the rails, crossbarsconnecting opposite hangers, and longitudinal bars connecting thehangers of the respective rails.

23. A guide for trolley-wheels comprising a pair of spaced substantiallyparallel guiderails having corresponding inwardly-dirccted flanges attheir lower edges with their opposite ends inclined downwardly,corresponding hangers rising from the rails, cross-bars connecting thehangers, and longitudinal bars connecting the hangers of the respectiverails.

t. An overhead-trolley system, the combination with a trolley-wire, of apair of guiderails located below and at opposite sides of the wire,hangers rising from the rails, crossbars connecting the correspondinghangers of the two rails across the top of the wire, and seats pendentfrom cross-bars and engaging the top of the wire to support the guide.

5. In an overhead-trolley system, the combination with a trolley-wire,of a pair of guide rails located below and at opposite sides of the wireand provided with corresponding inwardly-directed flanges, hangersrising from the rails and extending above the wire, crossbars connectingthe hangers above the wire, seats depending from cross-bars and restingupon the top of the wire, and a trolley-wheel for engagement with theunder side of the wire to run between the rails and provided at oppositesides with guide-rollers to run upon the flanges of the rails.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in the presence of two witnesses.

JOHN F. J AMESON.
